I recommend the book, Reincarnation Demon God, to you! The protagonist, Long Qi, transmigrated to another world and received the help of the Demon God System. From the beginning, he only had two wings, but later he became an Eight-winged Demon King. He fought with the Dreadlord, Chiyou, and others, and finally became a Demon God. I hope you like my recommendation, Mwah ~😗
